MACHINE FOR STRAIGHTENING WIRE.

SPECIFICATION forming part of Letters Patent No. 568,386, datedSeptember 29, 1896.

Application filed May 25, 1896. Serial No. 593,049. (N0 model-l To allwhom it may concern,-

Beit known that I, FRANK D VAN ARSDALE, a citizen of the United States,residing in Falconer, in the county of Chautauqua and State of New York,have invented certain new and useful Improvements in Machines forStraightening Wire; and I do hereby declare that the following is afull, clear, and exact description ofthe invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

The object of my invention is to make a wire-straightening machinewhich, while capable of straightening one wire, will also straighten anynumber of wires for which the machine may be desired, the number beinglimited only by the size of the machine and power to run it.

The improvement consists in a number of stationary frames provided withholes for each wire and a series of feed-rolls so arranged on each sideof a movable frame provided with holes to receive the wire and hung on apair of eccentrics, which impart to it a reciprocal and rotary motion,all of which will be readily understood from this specification and theaccompanying drawings, in which- Figure l is aplan view of my invention.Fig. 2 is a side elevation of the machine. Fig. 3 is a detailed view ofone of the stationary frames with bushed openings for the wires.

Similar numerals refer to similar parts throughout the several views. v

The metal bed 1 1 is secured to the top of a suitable bench or table. Tothis are secured the frames and feed-rolls through which the wires pass.Power is applied to pulleys 2 2 bythe one belt 2', the pulleys beingsupported on the ends of shafts 11 and 11, the shafts having suitablebearings in the stationary frames 3 and 4. These shafts support at theirother ends the pair of eccentrics 12 12, which bear and impart aneccentric or reciprocating motion to the movable frame 5. 10 on shaft 11drives cog-wheel 10', turning shaft 13, which by worm-gears 14 14 14 andcog-wheels 15 15 15 turn the upper feed-rolls 7 8 9 and the cog-wheels16 16, thus turning the lower feed-rolls. The pressure on feed rolls 7is regulatedby a weight suspended by Oog-wheel wires 19 19 to arms 1S18, said weight being beneath 'the table or bench, (not shown in thedrawings,) arms 1S 18 resting on the bearing at each end of upperfeed-roll 7, it being found that this device works better on this set ofrolls than the spring-tension or other devices, though such might beused. The tension of the other two sets of feed-rolls is regulated bythe springs 17 17 and four setscrews 21, thus attaining any tensiondesired in gripping the wires 20.

On account of the special wear from the strong leverage brought to bearon the wireopenings in stationary frame 4, I nd it necessary to bush theopenings, as shown at 4 in the several views. These bushings consist ofhollow bolts with a thread on their outer surface, by means of Whichtheyare secured in the frame and which make it easy to replace them withfresh bushingswhen required. The leverage on openings in frames 3, 5,and 6 not being so great, they do not need bushing. Of course frame 4might be left plain, but this would not be as well.

In operation the wires from the reels are first threaded through theopenings in frames 3, 4, 5, and 6 in succession and between thefeed-rolls, as shown, and attached to a suitable rope or steam feed,(not shown,) which aids in drawing the wires through the machine. Instarting the machine power is applied by belt 2 to pulleys 2 2, whichcauses the movable frame 5 to take a swift recipro eating and rotarymotion, stretching the wire .just beyond a point which would take up allthe slack which would naturally occur in the wire as it run through themachine. This stretching process takes out all kinks or unevenness ineach separate strand of wire. Pulleys 2 2 at the same time, bycog-wheels 10 10 and the worm-gears and cog-wheels above described, turnthe three sets of feedrolls. Feed-rolls 7 act as a stationary framebeyond stationary frame 6. It will thus be noticed that I have twostationary frames or iixed pointspof leverage on each side of themovable or stretching frame 5. A regular stationary frame might be putin between frame 6 and feecbrolls 7, but is not necessary, thefeed-rolls serving the same purpose.

Instead of two stationary frames each side IOO of the movable frame, onemight be used, but does not do as good Work, and I prefer it as shown.It might have one long bearing, but even this I find not as good as twolixed points ot leverage on each side of the movable frame. Movableframe 5 is nearer frame 4 than frame G, and the purpose of this is tohave the stretch of the Wire between frames fl and 5, and this is Whythe leverage is so great on the openings in frame 4.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In wire-straightening machines, having stationary frames, a movableframe or piece, mounted between the stationary frames on a suitable bed,and adapted to receive one or more Wires and through which they pass,the movable frame-piece being given a reciprocal motion to stretch theWire, suitable feed-rolls mounted on the bed to hold and draw the Wirethrough the machine, as shown and described.

2. In Wire-Straightening machines, a reciprocating frame suitablymounted and carrying one or more Wires to be straightened, havingstationary Wire-guides on each side of said frame, and feed-rollsproperly mounted to draw the Wire through the machine, as shown anddescribed.

3. In Wirestraighiening machines, a reci procating frame suitablymounted and carrying one or more Wires to be straightened, twostationary guides on each side of said movable frame, feed-rollsproperly mounted to draw the wires through the movable frame, andstationary guides, shown and described.

fi. In Wire-straightening machines, a reciprocating frame carrying Wiresto be straightened a uniform distance from a straight line in alternateopposite directions, the stationary frame through which the Wires passto the movable frame having bushings through which the Wires pass, asshown and described.

5. In Wire-straightening machines, the reeiprocating frame 5, suitablymounted and carrying one or more wires to be straightened, the movableframe 5 being placed nearer to stationary frame Li than to stationaryframe 6, as shown and described.

(5. In Wire-straightening machines, the bed l, l, on Which are mountedthe stationary guides 3, 4, Which are provided With shafts 11, 1l"having pulleys 2, 2 at one end and a pair of eccentrics at the other toreciprocate frame 5, as shown and described.

'7. In wire-straightening machines, the reciprocating frame 5 suitablymounted as shown, in eombin ation with shaft 13, provided withWorm-gears lli, 14, 1i to drive feed-rolls 7, 8, f), substantially asshown and `for the purpose set i'orth.

S. In Wire-straightening machines having bed l, l, suitably-mounteddriving-pulleys 2, 2, stationary frames or guides 3, 4, reciprocatingframe 5 carrying one or more Wires to be straightened, stationary frameor guide G through which the wires are again brought into line,feed-rolls 7, S, 9 to hold and assist in drawing the Wires through themachine, gears l0, l0, driving-shaft 13 having Wormgears let, 14, l-i,tension-springs I7, 17, and Weight-arms 1S, combined to operate in themanner shown and for the purpose set forth.

In testimony that I claim the foregoing I hereby sign my name in thepresence of two witnesses.
